Salesforce | document.getElementById(‘id’).value not working for apex:outputtext

If you have an apex:outputtext and you try to get its value in Javascript using document.getElementById(‘id of outputtext’).value(), that won’t work. The reason is apex:outputtext is translated to HTML SPAN element.

So

<apex:outputtext value=”Amount” id=”amntId”/>

becomes

<span id="amtId">Amount</span>

So to get the value use innerHTML instead – document.getElementById(‘id of outputtext’).innerHTML.
